Ok this may be a zebra in the midst of horses...but my breastfeeding listserv has been talking about bfding moms who have eating disorders...and their children's mimicry..so is your son around any younger girls..teenage girls that he MIGHT have seen this behavior and is now mimicing? OR does he maybe have a sore throat and this is his way of "telling" you his throat hurts/itchs whatever. Maybe you need to completely ignore the episodes for a few days and see if no attention makes the behavior go away. I'm kinda stumped. Let us know girl!
